I was already living with Chronic Fatigue Syndrome (CFS), so fatigue wasn’t new to me — but something changed. Not long after moving into a new flat, I noticed my symptoms intensifying. I developed a persistent cough that didn’t respond to treatment, my migraines became more frequent and severe, and my baseline energy plummeted even further. Gut issues flared up again, and I started reacting to foods and smells I’d previously tolerated. It felt like I’d lost the progress I’d made — and at the time, I didn’t suspect my environment could be playing such a significant role.
